Marcus, which is GS Bank, is certainly a retail product aimed at consumers.

Capital One, Discover, Ally, etc. were offering 4.35% at the peak. Not quite as good, but very decent for a savings account.

I don't know where you would draw the line under "major", though. But everyone knows BoA, WF, and Chase are trash when it comes to savings rates. They don't do it.

In Europe, HSBC (which is comparable in size to Chase and BoA) has reliably high saving accounts rates. HSBC UK was offering 5% until recently, I believe.

Hell, Fidelity pays 235 bps on checking and 435 on money market, which you can have them programmatically move everything over a fixed dollar amount in your checking into [1].
